HVAC office nightmare

I spend all day working in an office where I sit at a desk typing on a computer. The office is, usually, very comfortable. Outside, the temperatures range from the 80’s to the high 90’s, but we always stay cool in our building. Each of us, also, has a small fan attached to our desk that blows right on us. Most of the time, it is so cool in the building that I just leave my fan off. I even bring a sweater with me to work every morning. One very hot day, I entered the building to find the temperature inside much warmer than usual. I looked around and saw that everyone had their fans on and was sweating. As I walked to my desk, my coworker came up to me and told me the air conditioner had gone out in the entire building and that an HVAC service person would be repairing it that afternoon. I couldn’t believe I had to sit in this hot building all day while we waited on the local HVAC company to send someone over. I figured that I needed to make the best of it, so I took off my sweater, sat down, and turned my fan on. The cool breeze felt good, but I wished the air conditioner was still working. It never occurred to me how much I depended on a good quality HVAC unit to ensure I did a good job at work. After what felt like days, the HVAC repairman showed up and fixed our A/C. I was never so grateful in my life. Now, every morning that I walk in the door and the air conditioning is on I say a little prayer of gratitude for another day out of the heat.
